PONFY 110PCS Heat Shrink Butt Connectors Kit, Insulated Waterproof Electrical Wire Crimp Terminals, Butt Splice for Marine Automotive 3 Sizes

Works well, easy to crimp and a large assortment for the price.

Worked like it advertised, no issues!

When splicing wires on items stored in a potentially humid environment, such as my lawn tractor in my detached garage, covering the splice with heat shrink tubing is a must. I rewired my lawn tractor recently. I did splice connections by soldering the wires together, then apply heat shrink tubing using a heat gun. It was an arduous process even with an ultra-portable soldering iron such as the very popular TS100. If I had some of these connectors on hand, the re-wring would have gone much quicker. These connectors work with both strand and solid wires. I did a test crimp using 18-gauge wires (see photo). Connection was solid and the heat shrink tubing shrunk evenly and tightly. There’s no way I can pull this connection apart.I think these are very high quality connectors. As long as you use a decent crimper, and match connector size to wire gauge, these connectors won’t disappoint.

I ran out of one of the included size connectors, so I ordered this to stock up. I have previously used regular connectors that I had to install my own heat shrink tubing on, so I ordered the ones with the built-in heat shrink tubing to make connections that much easier.The connectors appear to be of good quality. They come organized in a case that holds the connectors well. I have not used any of them, but they fit my crimping tool fine. I expect that these connectors will work as well as any that out there.

I'm doing a lot of wiring in our van and have had some that don't work well which creates unnecessary problems. These work well and you can see if you have the wire in correctly.

It comes nicely organized.I've been using the red 22-16 connectors mostly. They all take a crimp well, and hold tightly without weakening.The heat shrink takes heat evenly and does a great job of sealing off the wires.They make great connections that don't pull apart.Overall a great kit.Highly recommended.

Not much to say except it comes in a little plastic case thats well sorted. The connectors do the job without much issue.
